BQ25600: VSET for JEITA Profile

Part Number: BQ25600

Hello team, 

For VSET setting for JEITA profile, there seems to be a mismatch in the datasheet. Please let us know which is correct.

On page 23 the JEITA voltage profile , my interpretation is

VSET =1, Charge voltage is 4.1V max

VSET =0, Charge voltage is VREG.

 

 

Then on page 40 8.4.8 REG07 bit 4

It looks like the following is true.

VSET =1, Charge voltage is VREG

VSET =0, Charge voltage is 4.1V

  • Sepeedah,

    The POR state of REG07[4] is 0. It should be the JEITA profile as shown by Table 4, which has 4.1V at high temperature range. REG07[4] =0 sets the VREG to 4.1V for 45C to 60C. We will correct the mismatch with the new datasheet revision.
